you are confusing the terms "rise and fall" with "pump and dump"

I am not. I emphasized in OP by clearly giving variable definitions.

Bitcoin pumps: % changes between 2 consecutive days >= 5%
Bitcoin dump: % changes between 2 consecutive days <= -5%

that's because unlike altcoins bitcoin is not pump and dumping!

I agree but I what I want to say is altcoins are suffered double pressure, from bitcoin price and from altcoin investors' uncertainty.

now look at their price against bitcoin and you will see that no matter if bitcoin rises or falls, altcoins are always dumping. (unless they have dedicated powerful pumping teams or some stand alone pumping hype going on).

I said about it in OP. Bitcoin rises, altcoins rise but rise less. Bitcoin falls, altcoins fall deeper. Statistics in OP are for bitcoin pumps/ dumps with my variable definitions. You can consider it as pumps/ rises or dumps/ falls, just pay attention on the threshold +5% or -5% I used.

if a stable coins increases or decreases in value then it no longer is a stable coin!
their volume and amount printed increase during the altcoin pumping seasons because they are used mainly in altcoin market.

Again, it is what I wanted to find and demonstrate with data. For now, let's ignore shady things behind stable coins (unlimited minting, etc.) and only look at price changes (in %). They are not actually stable if looking at p50, min and max values. Max of increase is at 12.74% and min of decrease is at -12.24%.

This has not yet taken into consideration the real trading price of 'stable coins' on marketplaces, locally. For local trades, things are much more different (wider range of changes).
